If you're talking about Matt's at Carolina Bike And Trike " Thunder Exhaust " I'm pretty sure those are not his....They look like Jardine to me with a " add-on " on the end

If they are Matt's the header pipe should not blue....If they are Jardine they will blue before you see 2,000 miles on them....I had a set of Jardine on one of my Valk's many moons ago.My guess they added the rear piece to get them pass the sadllebags ,lots of heat going off the Jardine exhaust and they ended about right in the middle of the saddlebags.
If they are "Jardine" you'd think they're logo would be stamped on them someplace, unless I'm not seeing it.
These ones are not blue, but the header pipes are not chrome ........ maybe they have be changed out......don't know. Stainless perhaps??

They have been used though, as the inside of the header pipes has a bit of carbon in them.
Not sure if the center pipe is an add on or not, I'll have to have a better look.

As far as what I paid for them, I'm thinking I'll keep that to myself for now just in case I don't like them and want to resell them. I think I did okay though according to what I see other systems going for.
"Blackduck", great info thanks for posting!
